# Should You Buy Symantec Corporation (NASDAQ:SYMC) At This PE Ratio?

Symantec Corporation (NASDAQ:SYMC) is currently trading at a trailing P/E of 16.8x, which is lower than the industry average of 34.2x. While SYMC might seem like an attractive stock to buy, it is important to understand the assumptions behind the P/E ratio before you make any investment decisions. Today, I will break down what the P/E ratio is, how to interpret it and what to watch out for. Check out our latest analysis for Symantec

### Breaking down the Price-Earnings ratio

The P/E ratio is one of many ratios used in relative valuation. It compares a stock’s price per share to the stock’s earnings per share. A more intuitive way of understanding the P/E ratio is to think of it as how much investors are paying for each dollar of the company’s earnings.

Formula

Price-Earnings Ratio = Price per share ÷ Earnings per share

P/E Calculation for SYMC

Price per share = \$27.54

Earnings per share = \$1.639

∴ Price-Earnings Ratio = \$27.54 ÷ \$1.639 = 16.8x

The P/E ratio itself doesn’t tell you a lot; however, it becomes very insightful when you compare it with other similar companies. Ideally, we want to compare the stock’s P/E ratio to the average of companies that have similar characteristics as SYMC, such as size and country of operation. One way of gathering a peer group is to use firms in the same industry, which is what I’ll do. Since similar companies should technically have similar P/E ratios, we can very quickly come to some conclusions about the stock if the ratios differ.

At 16.8x, SYMC’s P/E is lower than its industry peers (34.2x). This implies that investors are undervaluing each dollar of SYMC’s earnings. As such, our analysis shows that SYMC represents an under-priced stock.

### A few caveats

While our conclusion might prompt you to buy SYMC immediately, there are two important assumptions you should be aware of. The first is that our “similar companies” are actually similar to SYMC. If the companies aren’t similar, the difference in P/E might be a result of other factors. For example, if you are inadvertently comparing lower risk firms with SYMC, then SYMC’s P/E would naturally be lower than its peers, since investors would value those with lower risk with a higher price. The other possibility is if you were accidentally comparing higher growth firms with SYMC. In this case, SYMC’s P/E would be lower since investors would also reward its peers’ higher growth with a higher price. The second assumption that must hold true is that the stocks we are comparing SYMC to are fairly valued by the market. If this assumption does not hold true, SYMC’s lower P/E ratio may be because firms in our peer group are being overvalued by the market.

### What this means for you:

You may have already conducted fundamental analysis on the stock as a shareholder, so its current undervaluation could signal a good buying opportunity to increase your exposure to SYMC. Now that you understand the ins and outs of the PE metric, you should know to bear in mind its limitations before you make an investment decision. Remember that basing your investment decision off one metric alone is certainly not sufficient.
